This is a pie my ex-husband loved. It originally came on a phone bill that my grandmother had tucked away.....seems they would include a recipe with the phone bill way back when!! The 4 hour chilling time is not included in the prep time.
1Preheat oven to 375°. Combine the first 3 ingredients in a medium bowl; add eggs and vanilla, stirring well. Set aside.
2Combine chocolate and butter in the top of a double boiler; bring water to a boil. Reduce heat to low; cook until the chocolate and butter melt, stirring occasionally. Gradually add milk, beating with a wire whisk until well blended. Add the egg mixture, stirring well to combine.
3Pour the chocolate mixture into the pie shell. Bake at 375 for 45 minutes. Let cool slightly. Chill at least 4 hours. Garnish, if desired.
